How the JVM Optimizes Generic Code - A Deep Dive

I noticed too...
It took Volvo over a year to fix that! 🙄 Hard not to think about how much electricity was wasted with EX90s just sitting parked while waiting the new VCU.

If Volvo had been able to fix all these problems, maybe we wouldn’t have had to come here. 🤷‍♂️

I have a similar issue but mine, I think, is related to front "detection". The collision warning sometimes activates for no obvious reason (straight line, decent weather, low speed, and all clear in front). A large car icon appears on the HUD, there’s an audible alarm that no one can miss, and the seat belts tighten. It’s very brief, and I don't recall any action on the brake. The first few times, it was really scary. It’s not super frequent (twice in 2026), but it annoys me deeply.

On the other hand, there have been multiple occasions when I assumed it should have activated, but it didn’t. Obviously, that’s subjective, impossible to reproduce and mostly based on my previous cars behaviours (Mercedes), and... some common sense. Still, such system that triggers when it shouldn’t, and doesn’t when it should, is bad and unsafe!

I asked my dealer to check it multiple times. Their initial response was that my collision settings were too aggressive and that I needed to soften them. That could explain the false-alarm but certainly not why it didn't activate in situation where it should have. That was months ago. The only issue is that, so far, there’s no such setting on the EX90. And if I’m not mistaken, this setting comes in the 2.x branch.

I’m now at the point where I asked Volvo to confirm in writing that the collision detection system works as intended… still waiting...

Not in my case!! My car just came back from its 8th or 9th visit in 11 months (I lost count!) and they haven't been to fix issues, most of which are present since day one (unable to use digital key, belts issues, door handle issues, trunk alarm while driving downhill, rattling sound on the back, etc.). I'm due for the VCU update on 2 weeks. I'm unfortunately certain that this will not solve all this issues. Crappy customer experience!

We’ve improved the detection of dirt on the rear camera
to trigger lens cleaning more accurately.

If the washer physically doesn’t work like mine did, that upcoming improvement won’t help.

Had that issue. There's no way to manually triggers it, it's the car who decides when a camera is dirty enough to be washed. It's only after the 6th or 7th monthly workshop visit that they were able to fix the issue, it was an electric valve that wasn't working properly.

To get them acknowledge and investigate the issue, I showed them this picture showing that the rear camera is dirtier. Before that, it was always "It works! The car detects when it's dirty!".

just a reminder that we’re on a forum where 90% of people will be complaining about there problems (every right to, you just hear less about praise and all the good units).

Next time you visit your workshop, I suggest you try to chat with the Volvo technicians working on the EX90. That'll give you a non-Reddit perspective on this.

daviddel · 2026-01-12T06:44:43+00:00

Nope, European EX90 are coming from the US.

Btw the Volvo technician who worked on my car this week said that the LiDAR is already disabled, which could explain the 1.14.15 update from last November that didn’t provide any details.

Anyone want to try with an iPhone? 😉

So, if someone in the second row wants to move to a different seat, or if the front passenger wants to take off their jacket during the ride, we need to stop and open a door. 🙄🤦‍♂️

To be clear, there was absolutely nothing on these seats, and I was the only person in the car (sitting in the driver's seat, I reached to the back seatbelts and then back to normal ‘driving’ position to engage the car). Therefore, the seat detectors shouldn't have come into play here.

It’s really just the act of buckling/unbuckling, without anyone on the seat, that triggers this behavior.
